GUEST: He's always been important in my family. He hangs above the mantelpiece, and he follows you around the room. When we were children, we hid from him. Plus, my grandmother got him on her wedding trip in 1908.

APPRAISER: This painting is the work of Carl Moon, and it's dated 1907. Carl Moon had a studio in Albuquerque, New Mexico, between 1904 and 1907. He was born in the late 1870s. He died in the 1940s. The wonderful thing that you have to accompany this is the log of your grandmother's travels that was put together for you by another family member, and judging from your grandmother's travel log, she was on the Santa Fe Railroad, and she undoubtedly purchased this at El Tovar, which is up in the Grand Canyon. And it actually might be a work that he did after a photograph that he did in 1905 called Navajo Boy. There's a great similarity. He was an author, he illustrated children's books, he studied under a lot of very important people and all this history's paid off for him. He's increased in popularity over the past few years. His prices have risen accordingly.
